Application filed July'fl, 1925., Serial No. 42,104.

My invention relates to iin'rovements in headlight lensesfor motor ve icles and the object of my invention is to provide a headli ht lens that will eliminate the undesirable gfire from motor vehicle headlights and that will direct the light outwardly and downwardly onto the road in front of a motor vehicle in a manner best calculated to efiiciently illuminate the roadbed and make the driving of said vehicle safe and easy.

Another object of the invention is'to provide a headlight lens having a plurality of vanes formed on the front side thereof for preventing the light from passing upwardly and for directing the light downwardly onto a roadbed in front of saidlens, said vanes being arranged so that they prevent persons in front of a headlight on which said lens is installed from seeing the lamp bulb or 90 reflector or experiencing the glare that is ordinarily produced by the headlight lamp and reflector.

Another object is toprovide a headlight lens of one piece, integral construction embodying a lens portion having on its front.

side a plurality of normally transverse glass vanes which are thicker at the base and taper to thinner edges at the front and which are opaque or semi-opaque on one side and are inclined downwardly so that the front edge of the o aque portion of each vane lies in. substantially the same horizontal plane as the opaque f of the next vane there low, said vanes 85 being surrounded by an annular ring havinglan expanding inner wall and-formin a t shield and a. reinforcing member or the vanes, the ends of said vanes, havin the same angle as said expanding inner wa surface and said vanes projecting forwardly and sidewise beyond said surrounding ring, said. ring being narrow enough to'permit light to pass out at the sides, and the corners of the vanes that project beyond the I cone.

ortion of the base.

ring serving as a shield against upwardly are projects substantially on broken line 22 of Fig. 1 showing a fra ment of a headlight reflector'and retaining ring for the lens.

Fig. 3 is a fragmentary detached view'in side elevation of the headlight lens.

Like reference numerals designate like that it is cut: away as at 7 for a short distance at the bottom to better facilitate the shedding of light on the roadbed. The

outer wall 8 of the light shield 6 is pi'ef- I I erably cylindrical and at right an les to the lens member 5 while the inner wal 9 of said light shield 6 is inclined, outwardly from the lens member toward the outer end of said light shield in the form of an expanding A plurality of apart vanes 10 ,extendoutwardly from the front side of the lens member 5 within the area'enclosed by the light shield 6 and are all inclined in the same direction as shown the lens 5 and li ht shield ring 6 are preferably all forme or molded in one piece.

The normal operative position of this headli ht lens .is with the vanes 10 horizondering thevanes non-transparent.

The vanes 10 project outwardly further than the rin 6 and the edges of said vanes forwardl in alignment with the bevel or incline of t erin 6 so that said edges extend sidewise beyon the circular central portion of the lens through which integral parallel spaced ortion of said lens" Y big drawings clearly disclose a ner wall 9, of the light shield ring 6 and the outer flange of lens 5 will also preferably be ,coated with opaque of semi-opaque material to render said ring non-transparent.

When this lens is installed on a headlight lamp it will be apparent that some of the horizontal and most of the downwardl inclined rays of light from the lampbu b or from the reflector may pass outward freely between the vanes 10 but that some of the horizontal rays of light and all raysthat are inclined upwardly will strike the vanes 10 and be reflected downwardly or will be only partially transmitted by the opaque orsemiopaque upper surfaces 11 of said vanes. I

Rays of light tending to pass outwardliy and 'upwardly'from the sides of the hea light will be intercepted by the light shield ring 6 and by the overhangin edges of the 'vanes thus eliminating glare rom the sides. In looking at'a headlightequi ped with this lens an observer in front 0 .the same either on foot or in another vehicle will see the upper opaque or semi-o aque surfaces 11 of the vanes 10 and will not e blinded by the direct glare from thelamp bulb or reflector ofsaid headlight.

' The cuttin away of the ring 6 at the bottom permits the roadbed directly in front of a vehicle on which the headlight is installed.v The foregoing description and accom anyre erred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that such changes in the in- The outer wall 8 and im ight to pass downwardly onto,

vention may be resorted to as are within the 40 vanes projectingbeyond said ring at the sides p and said vanes being treated to render said vanes non-trans arent. v

2. An into a headlight lens, embodying a relatively at transparent lens portion, a circular non-transparent light shield ring extending outwardly from the front side of said lens wall, said rin having an expand inginner wall and having a portion thereof cut away to leave an opening at the bottom of said headlight lens and a plurality of normally horizontal spaced apart, downwardly inclined vanes extending across said within said light shield ring, the ends of said vanes rejecting be vond said rin sides, the ront edge 0 each of sai yanes bein substantially in pen icular to said flat lens rtion and that passes through the base of t e next ad'acentvane therebelow, said vanes being thic er at their base and tapering to a thin frontedge and the upper surface of'said vanes being treated to render the same non-transparent.
